I have Lightroom 6.10.1 on windows 10 with AMD Radeon HD7570 with latest Lightroom updates. I have an excess amount of memory. Whenever I do 2, or up to 5 action such as develop back to library Lightroom freezes and gives notice "not responding" I signed out out of Adobe and back in on this computer as it was upgraded from an HP Pavilion HPE where I had the same problem. This has be going on for about a year. I have to resort back to LR 5 to get anything done. Does anybody have any ideas how to fix this? Frank Patout [Removed by moderator.

If you haven't already tried this, go to the Lightroom preferences, Performance tab, and disable the graphics processor option and see if that has any effect on resolving the problem.
